I am sorry for all the people having problems, but my Prusa mjni is finally just workjng and happily printing all the stuff I throw at it. Its been having issues here and there forever. I just figured out that the hotend has not been assembled correctly (heatbreaker to nozzle seal was weak) which became a greater issue when switching to a 0.25mm nozzle. Now after I fixed it, it is just awesome :)
I used to be an avid modeler, but never got into printing for this one reason. It has to just work. Maybe the hobbyists are ok with troubleshooting, tweaking and fettling every little issue that emerges, but some of us just want to get (our) stuff done.
For that reason, it’s easier to just pay to get it done. But the whole idea of ‘click and print’ isn’t yet the reality.
It’s getting closer and closer. A good modern printer is largely fire-and-forget. Still takes some know-how, but far less than it used to.
